#4.5.3a
electron diffraction, including experimental evidence of this effect
Learners should understand that electron diffraction provides evidence for wave-like behaviour of particles.
#4.5.3b
diffraction of electrons travelling through a thin slice of polycrystalline graphite by the atoms of graphite and the spacing between the atoms
#4.5.3c
the de Broglie equation \(λ = \dfrac{h}{p} \)
